  • Subterranean well tool and slip assembly
    Patent number: 6354372
    Abstract: A slip assembly for anchoring a subterranean well tool, such as a packer or bridge plug, along the inner wall of a conduit, such as casing, against movements in at least one direction. As a series of radially aligned slip elements move from contracted to expanded positions, a continuous radial inwardly urging bias is applied against the slip elements to permit the slip elements to move to the expanded position in a substantially uniform plane of expansion. A subterranean well tool includes an elastomeric seal and the slip assembly.

  • Assembly and subterranean well tool and method of use
    Patent number: 6311778
    Abstract: A subterranean well tool which is manipulatable by a control mandrel between run-in and set positions within a wellbore having casing includes an assembly which provides a selectively operable lock to prevent premature activation of the assembly from the run-in position towards the set position until a predeterminable compressive load is carried through the well tool by the control mandrel to manipulate the assembly from a first initial position to an intermediate position and thereafter to a final extended position.
